HENRY IVHINFIELD, OF NFV YORK, N. Y.

STEAM-BOILER.

Specification of Letters Patent No. 19,669, dated March 16, 1858.

T o all whom it may concern.'

Be it known that I, HENRY VVHINFIELD, of No. 6 Vall street, in the city,county, and State of New York, have invented certain Improvements in theConstruction of Steam- Boilers; and I do hereby declare that thefollowing is a full, clear, and eXact description of the principle orthe character Awhich distinguishes it from all other steam-boilersbefore known and of the manner of making and using the same, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

Figure 1- is a section of a boiler with one longitudinal tube or flueconnected latitudinally with tubes or flues to the sides and verticallywith tubes or flues to the bottom, intended for locomotive engines. Fig.2-d is a section of a boiler with two longitudinal tubes or fluesconnected latitudinally with tubes or fines to each other and to thesides and also connected vertically with tubes or flues to the bottom.Fig. 3 is a section of a boiler with siX longitudinal tubes or fluesconnected latitudinally with tubes or flues to each other and to thesides and also connected vertically with tubes or fluesto the bottom.Fig. i is a latitudinal section of Figs. 5, 6 and 9 at (a, a). Fig. 5 isa longitudinal section of Figs. 7 and 8 at (Z9 b) showing the inside ofthe tubes or flues, fire box, ire water back and descending flue orchimney and boX for heating air and water. Fig. 6 is alongitudinalsection ofv Figs. 7 and 8 at (o c) showing the outside ofthe tubes or flues and boXes for heating air and water, with pipes toconduct the heated air into the boiler. Fig. 7- is an elevation of thechimney end of the boiler showing a section through Fig. 5 at (d d) ofthe boX and pipes for heating the air, also receiver and the pipes toconduct the heated air into the boiler. Fig. 8- is an elevation of thefront ofthe boiler showing fire doors, man-hole door, and cleaningplaces. Fig. 9- is a side elevation of the boiler showing cleaningplaces, boX to heat water and air, and pipes for conducting the heatedair into the boiler.

The nature of my invention consists in forming a steam boiler with theusual fire boX (B), with one or more or any number of longitudinal tubesor flues (E), latitudinal tubes or iues (F), and vertical tubes or flues(G), all connected together and to the sides, ends, and bottom of theshell of the boiler, as shown in Figs. l, 2, 3, 4, 5 and 6 in the usualmanner as heretofore described; making one of the strongest boilers inuse. The importance of this arrangement, is, the non-combustible gaseswill be separated from the combustible gases, which are, in consequenceof the combination and arrangement of all the parts forming the boiler,herein described, retained in said tubes or flues, and consumed asrepresented in Fig. 5, to wit: the pointed darts represent the light orcombustible gases, ascending after separation, which are then and thereconsumed, causing a great saving in fuel. The round or blunt ended dartsrepresent the heavy or non combustible gases descending down through thevertical tubes or flues (Gr), into and along the half tubes or flues(H), whichrepresents the bottom of the boiler to the descending flue orchimney (I), which are thereby carried ofll during the separation of thegases as heretofore described.

To insure the most speedy combustion of the gases, I apply a blowingmachine or equivalent to force air through the pipe (It), contained inthe boX (K), which2 air is there heated; and the heated air is thenforced into and through thereceiver (S), thence into the pipe (L), andsmall pipes (M), into the boiler through the latitudinal tubes or lues(F), and thence into the longitudinal tubes or flues (E), and verticaltubes or. flues (Gr), for the purpose of assisting the more speedycombustion of the combust-ible gases as hereinbefore described andtherein contained. By this process the intensity of heat generated is inproportion to the amount of oxygen forced into the boiler by the blowingmachine or equivalent; and consumed; resulting in great economy of fuel,which is the great feature of my invention.

The continuous combustion of the gases as heretofore described, in thetubes or flues '(E, F and G), during their separation, cre- .box andflues over the fire.

I place on the receiver (S), for heated air a regulating valve similar'in construction to a steam safety valve' for the purpose of increasingor decreasing the volume of heated air forced into the boiler throughthe small pipes (M). I also place on the boiler tyvo Ventilating doors(U), one on each side of the bottom of the chimney (II), as illustratedin Fig. 9 for the admission of cold air, which Will greatly assist theoperation of the boiler in retaining the combustible gases in the tubesor flues by opening one or both of said doors, and they can also be usedto remove any deposit at the bottom of the chimney.

The operation of cleaning the tubes or flues can With great facility beperformed through the oval holes (P), on the sides and ends of theboiler, and the dirt or refuse from the tubes or Hues Will fall throughthe vertical tubes or ues, onto the ground by first opening the movableor false bottom (Q), which can be replaced with ease.

To enable others skilled in the art to make and use my invention, I Willproceed to describe its construction and operation.

I construct my steam boiler of the usual materials in any of the knownforms, with a fire box (B), and furnace bars (C), in the usual manner;with a vertical Water back D), extending above the half tubes or flues(H), forming the bottom and a certain arrangement of one or morelongitudinal tubes or flues (E), as in Figs. 5 and 6, of any diameterproportionate to the size of the boiler, and connected (when more thanone are used) With one or more or any required number of latitudinaltubes or flues (F), of proportionate size (as in Figs. l, 2, 3 and 6),to each other, and to the sides of the shell of the boiler (A). The saidlongitudinal tubes or flues E), are also connected together with one ormore or any required number of vertical tubes or flues Gr), ofproportionate size to each other, and to the half tubes or tlues (I-I),forming the bottom of the boiler (A), which bottom (I-I), is formed oflongitudinal half circles or half tubes or flues, and inclosed by themovable or false bottom (Q), Working or moving on a hinge or ointforming a communication with the flue, chimney, or smoke pipe (I), thedamper (J), and the Ventilating doors (Il), by opening one or both asmay be required the combustible gases Will be retained in the tubes oriues of the boiler Without the constant use of the damper (J), asrepresented in Figs. 5 and 6.

In the rear of the boiler there is placed a box (K), as Wide as theboiler, and extending vertically about half or three-quarters the heightof the boiler, Which box (K), is heated with the gases from the boilerthrough the ends of the longitudinal tubes or ues E), and is constructedas shown in Figs. 6, 7, and 9 and acting as a heater to heatthe airpassing through the pipes (L) therein contained: to Wit: pipe (R),connects With a blowing machine for the purpose of a continual supply ofair; which air is heated in the pipes or compartments contained in saidbox (K), and forced into the receiver (S), thence through the pipes (L),and small pipes (M), or mouth pieces connecting said pipes L), With theboiler into the latitudinal tubes or flues as herein described.

In the rear of box (K), I place a receiver (S), for the purpose ofheating Water prior to its injection into the boiler by the force pump.Said receiver is heated on one side by the said box (K), and by thechimney or flue (I), passing up through the Water in said receiver.

Having thus described my invention, what I claim as ne\v,.original, anduseful, and desire to secure by Letters Patent is- The arrangement ofthe longitudinal, latitudinal or transverse and vertical fire tubes orflues as herein set forth. HENRY VVHINFIELD.`
